The average period of treatment was 7 months (range 5-11 months). No intraoperative complications developed. Postoperative complications were: superficial infection in 15 cases and wires breaking in five cases; no vascular or nervous complication were observed.

Consolidation at the docking site was achieved in 57 cases; formation of regenerating bone was regular in all these patients. In the four patients in whom consolidation was delayed, a bone grafting was performed.

A residual deformity, represented by a slight angular deformity at the previous nonunion site (max 4°), was observed in five cases. The articular function was good during the treatment, with a moderate limitation of knee flexion, and ankle flexion and extension. It had become almost normal a few weeks after the treatment ended and the fixator was removed.
